Aftermarket DIC for Trailblazer?

Hey guys I have a 2008 trailblazer and it doesn't have a (DIC) I'm wondering if anyone has installed an aftermarket one? This truck has the AFM 5.3l V8 and I'd like the ability to see the instant MPG and also Avg MPG.

Thanks to anyone that answers to this post.

I asked around and all it will take it buying a used console that did have DIC in it and also changing some things like a new clock spring and adding in couple of new wires in your steering wheel. (I guess from the new buttons to the display?) I'll see if I can get some better directions. Anyone done this?
